I have been experience sore breasts, fatigue, nausea and cramping. Craving for junk food and headaches along with aversions to familiar smells. Took pregnacy test @ two weeks after the sore breasts started and it was negative. Had unprotected sex during ovulation in Nov and that period came late. December and January were on time. It has been about 9 weeks now. However, the symptoms have not gone away. Period ended Thursday and I am still seeing bright red blood when I go to the bathroom.What is the chance that I maybe pregnant or could this be something else?
